I was just wondering about the car. It is a 1997 4door 318is 5speed with a downing/atlanta supercharger on it. I purchase the car for 7000.00. What boost is the sc good for and what would help with more power? was that a good price ? and what upgrades should i do. it just stock with 120,000 miles and the supercharger and short shifter, light weight wheels. i not sure on how to post pictures but i will try.
